Abstract
An imaging system (1) comprises a transmitter (3, 6), a receiver (3, 4, 6), an antenna array (2); and a controller (4, 5, 10, 11) for directing the transmitter, the receiver, and the antenna array to scan a volume containing an object. The controller has multiple distributed processors (15) to calculate antenna control pattern data during rim-time. The processor (4, 5) assesses misalignment of antennae using a receiver placed in the imaging volume, and monitors level of energy received by the receiver and compares it with a reference energy level. Also, the controller performs on-the-fly modification of antenna control pattern data according to real time conditions such as mechanical misalignment of the transmitter, the receiver, or of one or more antennas. The controller may generate three-dimensional offset vectors to provide a profile of the offset across the scan volume, and the position of an antenna may be moved to compensate for the mechanical misalignment.
